i use emacs. what the heck do i need gem windows for? :-)

actually, i doubt i will have time to write something from scratch. so
let me modify this: i will post more a skeleton of an application which
may need fleshing out. sort of a tutorial.

i have some code laying around for passing messages between DAs and
applications. does this sound interesting enuf? i originally wrote it
for a MIDI application. the DA would pass data from the application to
a MIDI device (a sample dump, in this case), and pass MIDI info to the
appl. the idea was to use DAs more like device drivers, but with a
dialog. it worked well.

elements of this is:

	GEM messages, care and feeding of
	shared memory
	protocol development
	DA/AP message passing
	having an appl wake up a DA, etc.

it will take some time to get it in a form i can explain (since i forgot
most of what i did long ago). so...if at least 10 people say "do it", i will.

another thing i *could* do is to pass along a ladder-style menu system:

	 _______________
	|		|
	|_______________|
	|******* _______|_______
	|_______|		|
	|	|_______________|
	|_______|******** ______|_______
	|	|________|		|
	|_______________||______________|
			 |**************|
			 |______________|
			 |		|
			 |______________|

i wrote. it was convoluted and not general, however, but worked well. i
was planning on writing a code generator to make it general. oh, well...
one of these days...

a *simple* text editor is relatively easy. just shovel ed(1) into
a gem wrapper. the only tricky parts are scrolling: v_gtext/vro_cpyfm
or whatever instead of printf. i have a working ed(1) if you want src. it
is small, simple, and easy to modify. but i think IPC (or the menu thingie)
is much more interesting.

a better idea would be an MGR editor. done like apollo's display manager
editor. now THAT would be slick.

Ha Ha. :-) To Paraphrase A Popular Saw Heard Around These Parts: "Not
Shifting At Beginning Of Sentences Saves Many, Many Keystrokes, Not To
Mention My Little Pinky".

thanx for the code, BTW...
